Two million years ago, humans were shorter and (1)lighter/more intelligent than they are today. Their ears and their noses (2)were/weren't sensitive because they were hunters. In the next half million years, our evolution (3)will/won't continue. If we colonise space our bodies (4)will/won't adapt to the new environment. If we (5)evolve/become extinct, robots will probably survive.
